Image on ST2320L monitor connected by HDMI cable does not fill screen

I have a Dimension 8300 desktop with ST2320L w/s monitor. The monitor was quite happily working with a VGA cable connection.

Today I bought a HMDI cable and replaced the VGA cable whilst computer was off (i.e. now just connected with HMDI cable). On turning on, an image is displayed but with black bars around all edges: about 1cm top/bottom, 2cm left/right.

I then went into Control panel and checked resolution which shows as: Dell ST2320L_HMDI, 1920x1080 (recommended) and Landscape.

I then entered monitors own settings by clicking on the touch buttons on bottom right corner of screen. Whether input source is auto selected, or I select HMDI myself makes no difference. For Display settings "Fill" as opposed to 4:3 is selected. The Horizontal/vertical position options are greyed out. The Menu confirms the resolution displayed as 1080p, albeit with the black bars around all sides I have.

Hello, Mark! I experienced the same issue with Inspiron Zino. The "scaling" bar has to be in ATI Catalyst utility. The problem is that the latest versions of ATI Catalyst does not have a "scaling" bar! I had to remove all ATI drivers and software and install separately new drivers and ATI Catalyst ver. 10.5. It solved the problem.

On the START menu I now have an icon for the Catalyst Control Centre, but clicking on it, just has my computer thinking about things for a coupleof seconds without loading anything foor me to tweak the scaling option mentioned above. Right click on properties for this programme reveals it is for this .exe file:

Have you got NET framework installed as it's needed to get the CCC to function properly?

Also what version of windows are you using (including version of service pack)? If using windows 7 you'll need to have SP1 installed.

Quoted from the requirements:

The AMD Catalyst Control Center/ AMD Vision Engine Control Center requires that the Microsoft® .NET Framework SP1 be installed for Windows XP and Windows Vista. Without .NET SP1 installed, the AMD Catalyst Control Center / AMD Vision Engine Control Center will not launch properly and the user will see an error message.

Once you get CCC working you need so set your scaling like in this pic.

I find the easiest method for a clean install of the latest catalyst suite is to run the latest installer suite. You'll get to a screen that has 2 options, 1- install software or 2- uninstall all ati software. Click to uninstall and you'll be asked to reboot to finish the uninstall.

Once rebooted and back to your desktop, rerun the installer but this time choose the install software option. Hopefully this should sort you out.

To get to the CCC panel I've posted a pic of above, right click your desktop> catalyst control center.

Also, within Control panel / Display / Screen resolution / Advanced settings, one of the tabs is for Catalyst Control Center. I click on the button and the computer thinks about things for a couple of seconds, but then does not open it. I get no error messages.
